In the US itâs from lead bullets, they scavenge a lot so they eat it from shot animals.

No, itâs due to these birds eating other human-hunted animals, either alive or their abandoned interiora.

Are folks killing animals and not eating them or butchering them for their materials? Thatâs fucken horrid if so.

My guess is that migratory waterfowl eat lead shot when âgrazingâ the bottom of wetlands. This bio-concentrates the lead in eagles when the prey on ducks and such.

@vaultdweller013@sh.itjust.works Probably that too, but the major cause is that hunters eviscerate the prey on the spot, so that the meat will last longer and retain a better taste.
Despite not being a biologist, it is a topic I deeply care about. I have held a few presentations too, for friends and university colleagues.

Aight I see how thatâd happen. Forgot about the reservoir effect.
